“…The analysis of the optic disc is an important step in the diagnosis of glaucoma and therefore a careful clinical observation should be performed to separate glaucomatous changes from normal data (1)(2)(3) . Previous studies have proposed the use of ultrasound examination (US) as an ancillary method for the assessment of glaucoma patients, especially in cases which optic opacity is present (4)(5)(6) .…”

Purpose: To investigate the correlation between the measurements of the cup/ retrobulbar optic nerve diameter (C/OND) proportion obtained by high-resolution 20-MHz B-mode ultrasound (US) and those of the cup/disc ratio (C/D) obtained by fundus biomicroscopy (BIO) and optical coherence tomography (OCT). Methods: Thirty eyes of 15 glaucomatous patients with any C/D proportion were studied. All patients underwent examination of the vertical C/D by BIO with a 78D lens and time-domain OCT analysis, as well as the vertical C/OND proportion using 20-MHz US measurements. All data were analyzed by correlation and agreement tests. Conclusions:The results demonstrate that B-mode ultrasound examination with a 20 MHz probe can be a good additional method for the evaluation of the C/D ratio in glaucomatous patients, and may be considered as an alternative gross tool in glaucomatous patients with optic media opacities.
